Black Mesa Source Trailers
Black Mesa Source Team
These are the two previews for Black Mesa Source, the teaser and the trailer, from 2007 and 2008 respectively. Black Mesa Source is a modification to remake of the game Half Life in the Half Life 2 engine, entirely redoing the assets and improving much of the games look and feel.
The teaser is described as "The video features level flythroughs, and all the filming and composition was done by the extremely talented Monkey-Junkie, with the music being created by our sound artist, .Plink."
The trailer contains much more complete footage, with in game models, new voice acting work and displays of the redesigned levels and music.
